|2x + 6| - 4 = 20
First, add 4 to both sides. / Your problem should look like: |2x + 6| = 20 + 4
Second, simplify 20 + 4 to 24. / Your problem should look like: |2x + 6| = 24
Third, break down the problem into these 2 equations. / 2x + 6 = 24 and -(2x + 6) = 24
Fourth, solve the 1st equation: 2x + 6 = 24
Subtract 6 from both sides. / Your problem should look like: 2x = 24 - 6
Simplify 24 - 6 to 18. / Your problem should look like: 2x = 18
Divide both sides by 2. / Your problem should look like: x =

Simplify

to 9 / Your problem should look like:
x = 9
Fifth, solve the 2nd equation: -(2x + 6) = 24
Simplify brackets. / Your problem should look like: -2x - 6 = 24
Add 6 to both sides. / Your problem should look like: -2x = 24 + 6
Simplify 24 + 6 to 30. / Your problem should look like: -2x = 30
Divide both sides by -2. / Your problem should look like: x =

Simplify

to

/ Your problem should look like: x =

Simplify

to 15. / Your problem should look like:
x = -15
Sixth, collect all of your solutions. / Your problem should look like: x = -15, 9
Answer:
x = -15, 9 (C)
Answer: 1988 x 10^-3
Explanation:
(8 x 1011)/(4x1017)
= 8(1000+11)/4(1000 + 17)
= 2(1000+11)/1017
= 2022/1017 is approximately 1.988
Which in standard form 1988 x 10^-3

Answer:

Step-by-step explanation:
we know that
<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
To calculate combinations, we will use the formula

where
n represents the total number of items
r represents the number of items being chosen at a time.
In this problem

substitute

The product of any integer (let that any integer be' x') and '-1 ' will be -
if the integer is positive then the integer will be negetive

if the integer is negetive then the product will be positive

if the integer is 0 then the product will be 0
as any no. multiplied by 0 is 0
